DUST-COLLECTOR.

SPECIFICATION forming part of Letters Patent No. 655,635, dated August7, 1900. V Application filed .Tuly 1,1899. Serial No. 722,570. (Nomodel.)

To all whom it may concorre.' l

Be it known that I, ORVILLE M. Monsn, a citizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,have invented certain new and useful Improvements in Dust-Collectors,ofwhich the following is a specification, reference being had therein tothe ,accompanying drawings.

The invention consists in the construction of a dustoollector embodying`a chamber having an air-inlet for the dust-laden air and exit from thechamber, across which are arranged brushes and means for jarring oragitating the brushes and for sweeping up the collected dust.

The invention further consists in combining such a dust-collector withan initial dust collector or separator which Will collect all but thefine dust and use my improved dustcollector as an attachment thereto forthe purpose of collecting this fine dust.

The invention further consists in the construction, arrangement, andcombination of the various parts, as more fully hereinafter described,and, pointed out in the claims.

In the drawings, Figure l is a sectional perspective view showingmyimproved dustcollector attached to a dust-separator or dustcollectorof the general type shown in my previous patent, No. 403,362, of May 14,1889. Fig. 2 is a oross-section through the upper part of Fig. l. Fig. 3is a detail section illustrating the construction of the vibrating meansfor the brush or broom sections.

I have shown my dust-collector as circular in form and comprising theheads A and B. In this case the head B forms the top of the initialdust-collector, the body of which is palpable dust, so light as not tobe affected by the centrifugal action in such momentum dustcollector,and it is to collect the dust in the air passing through this air-enitthat I- have shown my improved dust-collector applied.

The head A, I have shown secured to a shaft G, which is journaled insuitable bearings in the top of the momentum dust-collector. This isdriven by any suitable meansas, for instance, by a Worm-gearH on a shaftI, meshing with a worm-WheelJ on the upper end of the shaft G. Securedto the edge of the plat-e or end A are the brushes K, so ar= ranged asto cover the exit from the chamber Within. In this construction thebrushes K form the entire circumferential Wall of the dust-collector.These brushes are preferably formed of a brush-head L, having the pins Mslidingly secured through bearings in the top A, with springs N adaptedto hold the heads normally in their upper position. These sections arepreferably of such length as to extend between the radial plates ordividing-Wings O, Which are secured to the under side of the head A andextend down into close proximity to the head B, thus dividing thedust-chamberinto a series of sectors, as plainly shown in Fig. 2.

It Will be obvious from this description that my dust-collector, asherein shown, consists of a circular chamber, the dust-laden air beingdelivered thereinto from the aperture F, and that the air may find anexit through that Wall thereof which is formed by the brush.

I have found by practical experiment that such dust as comes from theeye of the molnentum dust-collector is of such a nature that uponstriking an object in its path it Will adhere thereto, very much as Wetsnow ad' heres to the sides of trees when blown by the wind. I thereforefind that with brushes of, for instance, broom-corn or similar materialarranged as described in relation to the dustchamber if the dust-ladenair is blown therethrough the dust will adhere to the brush, While theair Will iind a practically-'unobstructed passage throughthe brush.

It will be observed that the 'brush forms the Wall of the dust-collectorand that there is a free and. unobstructed exit for the air through thatwall and no perforated cloth or Wall-through which the air mustsubsequently be passed and which would make a back pressure and to whichany small particles of dust which might pass through the brushes wouldadhere. I Iind with such a device that the air from the eye of such amomentum dust-collector after passing through my improved dust-collectormay be discharged with impunity into the mill.

The radial wings or blades O divide the dust-chamber into a series ofcompartments, as before described, each one of which extends from theair-inlet section to the brushes at the other end.

In order to clean the brushes of the accu mulated dust, I arrange at onepoint a cover P for a section of the air-inlet passage F, as plainlyshown in Fig. 2, this plate being sufficiently long or Wide to cut offfrom the air inlet opening an entire section of the dustchamber. Whilethus cut off, there is of course no air circulation through that chamberand there is formed what I call a deadair chamber therein. While the aircirculation is thus shut off or the dead-air chamber is formed I knockor shake the brushes by any suitable means and arrange beneath the samea discharge-spout Q, into which the dust therefrom will pass. Thepreferable means which I employ for cleaning the brushes of dust consistof a toothed cam R, secured above the machine, which is adapted to beengaged by a pin S, which projects from the brush-head, the brush-headbeing through the head A in the casing in the travel thereof, as shownat the left hand in Fig. 2 and which is illustrated more particularly inFig. 3.

It will be seen from this description that through the greater part ofthe travel the dust from the eye of the momentum dust-collector willrise into myimproved dust-collector and pass freely through thebrush-walls thereof Without any materialimpeding of the air-,current orback pressure on the device and that at one or more points of theoperation the air circulation is shut cti", and while thus shut oit thebrushes are cleaned.

I preferably make lthe plate Padjustable by any suitable means-such forinstance, as theradial slots a, in which clamping-screws may be engagedto clamp the cover or plate in the desired position. This I preferablyarrange so that there may be a slot T leading into .the

eye of the momentum dust-collector at such points therein that there isa draft from the dust-chamber, so that at the time the brushes areshaken or vibrated whatever air pressure or circulation there is isinward, and thereby I prevent any dust from being discharged into theroom While the brushes are being cleaned.

I have shown and I preferably employ a iange or strip U around the edgeof the head B, extending a slight distance up the brushbody to insure atight joint at the lower or free end of the brushes.

That I claim as my invention is 1. A dust-'collector comprising twocircular heads, and a cireumferentiallyarranged brush, a series ofimperforate radial division- Walls forming a series of chambers, anair-inlet common to all the chambers at the center of one head, meansfor shutting off the chambers successively, and means for vibrating thebrush of the shut-off chamber.

2., A dust-collecting device comprisingamomentum dust-collectorhavin g atapering body and an apertured head, of a dust-eol1ectorap plied theretocomprising the head A, radial imperforate division-Walls securedthereto, means for rotating the same, a brush formed in sectionsextending between the edges ofthe head A and the head of the momentumdustcollector, means for vibrating sections of the brushes, and adust-spout over which the brushes are vibrated.

3. Adust-collectingdevice ccmprisingamomentum dust-collector having ataperingcasing and an apertured head B, of a dust-collector applied tothe head and consisting ot' the head A complementary to the head B,means for rotating the head, a series of circumferentiallyarrangedbrushes secured to the head A and extending to the head B, a series ofradial apertures dividing the space between the head into a series ofchambers, a cut-off between the opening in the headB and each ofthechambers successively during the rotation thereof, and means forvibrating the brush during the eut-off period of such chamber.

4.-. A dust-collecting device comprisingamomentum dust-collector,consisting of a casing having an apertured head and a tangentialair-inlet, of a dustcollector applied to the aperture in the head andcomprising a brush, arranged over the exit therefrom, means for shuttingoft communication between the exitopening and the chamber within thecasing and connecting it with a reverse-operating draft, and means forvibrating the brush during such shut-ofi' period.

5. A dust-collecting device comprising a tapering easing, a tangentialinlet for the dustladen air, a dust-outlet at the small end, animperforate top having a central aperture for the purified air, animperforate head above the top of the dust-collector forming a chamberbetween the two and brushes extending between the head and top throughwhich the air from the chamber last referred to must pass in its exitand means for vibrating or shaking said brushes intermittently,

In testimony whereof I affix my signature in presence of two witnesses.
